The 1953 musical classic "Gentlemen Prefer Blondes" was a showcase for its two charismatic leads, Marilyn Monroe as the diamond-obsessed Lorelei Lee and Jane Russell as her witty friend Dorothy Shaw. While Monroe's performance is iconic, it was the established star Russell who received top billing for the film. Sixteen years later, Maggie Smith delivered a tour-de-force performance as an unconventional Scottish schoolteacher in "The Prime of Miss Jean Brodie," a complex role that earned her the Academy Award for Best Actress and remains one of her most acclaimed.
